Ilatented Oct. 15,1912.

Application filed December 4, 1911. Serial No. 663,774.

To all whom it may concern:

Be it known that I, ERNST I-IAUrr, a sub ject of the Emperor of Germany, and a resident of Naumburg-on-the-Saale, Germany, have invented a certain Improved Toothpick-Making Machine, of which the following is a specification.

Machines for cutting tooth-picks out of an intermittently fed wooden strip are already known. It is also known to combine such machines with means for printing the tooth-picks on one side with advertisements.

The present invention relates to a machine of this kind and consists in the various improvements as hereinafter set forth and claimed.

In the first place a cutter is provided which, instead of having the form of a tooth-pick, as in the old machines, has the form of the portion which is cut out from the strip between two adjacent tooth-picks. The tooth-picks are therefore formed by the cutting away of these intermediate portions which are discharged through the aperture in the matrix. This arrangement allows a cutter of a very simple, adjustable construction to be employed, and the points of the tooth-picks can moreover be cut to any de sired nicety without the constructional details of the cutter having to be taken into consideration.

In the second place means are provided for printing the tooth-picks on both sides,

printing as well as feeding and cutting elements being all operated from the same shaft.

The feeding of the strip is effected by means of an obliquely disposed fork which rests with its lower, milled ends against the strip and which is pivoted to a slida'ble rod,

the movement of said rod being limited toadjust the feed.

In the accompanying drawings the lnvention is illustrated by way of example, Figure 1 representing a vertical longitudinal section of the machine, Fig. 2, a cross-section of the same on the line A-B of Fig. 1, and Fig. 3, a cross-section on the line C--D looking in the direction of the arrow I. Fig. 4 is a side view of the inking device for the printing block, Fig. 5, a plan of the same, Fig. 6, a side view of the cutter, Fig. 7, an inverted plan of the same, Fig. 8, a horizontal section of the matrix for the cutter, and Fig. 9, a vertical section of said matrix.

The wooden strip 1 is fed intermittently in the direction of the arrow 11 through a guide-way in the machine between the printing blocks 3 and t and over a matrix 5. 1n the upper part of the machine frame a shaft 11 is rotatably mounted from which all the movable elements of the machine are operated. The shaft is fitted with a flywheel l0 and may be driven either by mechanical or hand power for which latter purpose the wheel 10 is provided with a handle 9. The feeding of the strip is effected by means of a fork 2 which is pivoted to a vertical, axially slidable rod 1-1 and which is supported in an oblique position against the strip, the lower engaging ends of the fork being milled to insure the necessary frictional engagement with the strip. A spring 15 tends to raise the rod 14 which is depressed in opposition to said spring by a tappet 12 mounted on the shaft 11. Between the tappet 12 and the upper end of the rod 14 the free end of the lever 13 is interposed. This lever is pivoted to the machine frame and it abuts against the end of a screw lti which limits the upward movement of the lever and of the rod let. A depression of the red by the ta ppet 12 causes the strip 1 to be fed forward by the fork 2 which slides on the strip during the rearward movement. By adjusting the screw 16 the movement of the elements, and thereby the feed of the strip, can be regulated.

The printing block 3 is carried by a vertical ram 21 which is slidably held in a dovetail groove in the machine frame and which is controlled by a pivoted lever 90. The latter is linked by means of a connecting-rod 19 to another pivoted lever 18 which is rocked by a tappet 17 mounted on the shaft 11. An aperture 22 is provided in the guide-way to admit the printing-block 3 to the strip which is supported by a platen arranged above the slot. The block 4. is carried by a slidable rod which at its upper end is provided with a roller 24, the latterserving as abutment for a tappet E23 by means of which the rod is depressed in opposition to a spring 27. This rod and another rod, carrying the cutter 6 and operated in exactly the same manner, are divided into two parts between which a screw 26 is interposed, such screw allowing the position of the lower end of the rod relative to the strip to be adjusted. Each part of the rod has its separated guide-way, and the spring 27 acts on the lower part so as to clamp the upper part between the latter and the tappet 23.

For inking the printing-blocks the following arrangement is provided: An inkroller 28 is carried by a dove-tailed slide 29 which is reciprocated so as to pass the roller across the block as soon as it is withdrawn from the strip 1. The slide for the upper block is reciprocated by a double-armed lever 36 which is pivoted at 42 to the machine frame and connected by means of a rod to a ring 44, the latter being arranged on an eccentric 43 mounted on the shaft 11. The slide of the lower block is moved at right angles to the former one by a double-armed lever pivoted at 88 and engaging, by means of a pin 39, a cam groove 4.0 in a cam t1, the latter being mounted on the shaft 11. Each roller 28 receives its ink from a roller 30 and passes from the latter roller over a distributing disk 0:, these elements being fitted with ratchet-wheels and being rotated by pawls 31 engaging such wheels. The pawls 31 are connected to a slide 32 which is normally held by a spring 33 in the position shown in Figs. 4- and 5 and which is moved in opposition to said spring by an arm 35 projecting from the lower end of the lever 86 or 37 respectively, the slide having a lateral projection 33% which engages said arm. Detents 31, connected to the ink-receptacle, cooperate with the pawls for keeping the elements in rotation.

After the tooth-picks have been printed, they are severed from the strip by the cutter 6. The latter consists of two resilient knifeblades which are clamped between two jaws 46. From these jaws, which have a central position on'the blades, the latter diverge toward both ends, the divergence being ad j usted by means of screws 47 held with their screw-threads in one blade and abutting, with their ends against the other. The slot of the matrix 5 is shaped in conformity with the cutter, it being narrow in the middle and widened at a constantly increasing gradient toward both ends. When the cutter is applied to the strip a piece, having the form 1 Should it be desired to print the toothpicks on one side only, one of the printingblocks may be put out of action.

I claim 1. In a tooth pick making machine of the character described, a guide-way, means for feeding a wooden strip intermittently and positively through said guide-way, a print ing-block arranged underneath the guideway so as to print the strip through a slot in said guide-way, a platen arranged over the slot so as to support the strip, another printing-block arranged above the strip at such a distance from the former block, determined by the positive feed, as to print the strip opposite the first imprint, a cutter arranged in advance of said printing-blocks so as to form the tooth picks by cutting away the portion between the imprints, a driving shaft, and connections between said shaft and the feeding device, the printing-blocks and the cutter causing the latter elements to cooperate, substantially as set forth.

2. In a tooth pick making machine, a cutter composed of two resilient knife blades clamped together in the middle and diverging toward both ends, screws fitted in the ends of one blade and abuttingagainst the ends of the other blade for adjusting the gradient of divergency, and a matrix arranged underneath the cutter so as to cooperate with the same and receive the waste severed by the cutter from the strip from which the tooth picks are made, substan tially as set forth.
